Can you try copying the openSUSE-11.3-DVD-i586.iso from the network share to your local disk (where the VM is running), and check the file size and md5 checksum? We'd like to rule out the possibility that the network share is truncating the file or something like that.

Thanks for the new info. That's helpful, but we're still having trouble reproducing. Can you also tell us what the VM was doing before you rebooted (ctrl+alt+delete)? Was it booted into another OS (Windows 7 x86?), or trying to PXE boot, etc?

Also, would it be possible to compress and upload the debug.vmem and debug.vmss files? It would be best to get the matching vmware.log, vmware-vmx-debug.dmp and vmmcores.gz files for the same run as well.
